Tornado Watch may be needed in the next hour or so for Northeast Nebraska and into Iowa. First of many I'm afraid.

The first of many PDS watches I'm afraid also. Destructive large long lived killer tornadoes are likely in this entire region. PDS's are not unlikely at this point.

I think it will be a red parallelogram feast this afternoon.

Or orange....as MANY of those will be PDS tornado watches.

Yup, orange or very dark red. Either way, It won't be your typical tornado watches as PDS's are likely in numerous numbers. With any tornado watch though treat it as a PDS watch as we could see destructive tornadoes, hail 4 inches in diameter, thunderstorm wind gusts to 80 mph, and dangerous lightning.
